Yeah, rear output is same config 1350 or 1354.
×2, a front driveshaft from a D35 TTB-equipped truck should fit right in there if you have the FM145 trans. It has a dual-cardan CV also, good if you have (or plan to install) a suspension lift. You'll also need the mating flange/yoke to fit it to your rear axle pinion flange (you can grab this from the rear driveshaft of pretty much any '90-'97 RBV).
If you have the A4LD, you can still do this swap, however you will have to have the driveshaft shortened about 2" at a driveline shop (probably be <$100).
